To the best of my knowledge, there are only three keys: the tubular XX2247 which is used on most -8s and -11s including my 8/es and 11/34, the one that looks like a filing cabinet key used on just a few machines (all keyed alike), and the plastic "key" used on later Vaxen as well as the 11/24 - albeit in a variety of colours of plastic.
There's also a XX3651 used on some PDP-11 models. I have both that and the XX2247 in mint condition. :)-Rick
